Maul PLAST profile pipes have a cross-section that is optimal in terms of high water
capacity and low height. It is recommended for use as small bridges and in places where there is a vertical
restriction for the passage of round or ovoid pipes.

Plast pipes are reinforced concrete non-pressure pipes with polyethylene protective jackets. The polyethylene protective jacket has T-shaped anchors that are monolithically embedded in the pipe walls during its formation, ensuring reliable adhesion to the pipe. The protective liner is made of low-pressure polyethylene (LDPE) in accordance with GOST 16338-85 and is designed to ensure durability (at least 50 years) and water resistance of sewer pipes when operating under conditions of highly aggressive environment inside the pipes against concrete (reinforced concrete). The HDPE is resistant to concentrated hydrochloric, carboxylic and hydrofluoric acids, oils, fats, alkalis, salt solutions, resistant to gasoline, low temperatures, plastic and has good impact resistance.
